Introducing the ClinCalc DrugStats Database and the 2017 Top 200 Drugs

We’re excited to announce the launch of our newest product at ClinCalc.com — the DrugStats Database! This database provides free, web-based access to outpatient prescription utilization statistics for the United States encompassing more than 3 billion prescriptions annually.

Features of the ClinCalc DrugStats Database

By leveraging the database, users can identify trends and compare usage of approximately 500 different outpatient medications. A few examples include:

1. What is the most common medication prescribed in the US?

In the most recent year on file (2014), lisinopril took the highest position by about 15 million more prescriptions compared to the second place medication, levothyroxine. As shown from the DrugStats database, the usage of lisinopril has seen a steady increase over the past decade:

2. What is the most common angiotensin receptor blocker (ARB) on the market?

Nearly all medications within the database have at least one Established Pharmacologic Class (EPC) provided by the FDA. In reviewing the EPC page for ARBs, losartan (and the combination of losartan/HCTZ) make up about two-thirds of the entire ARB market in the United States:

3. The “Top 200 Drugs” covers about 90% of all outpatient prescription drugs

Many colleges of pharmacy implement a “top 200 drugs” or “top 300 drugs” list for students to memorize basic facts about each medication (brand/generic, drug class, mechanism of action, etc.) in order to expedite their basic, foundational drug knowledge.

In the United States, there are approximately 500 active ingredients that are filled annually (in a variety of different dosage forms and salts). The 200 most common (40% of 500) represent 90% of all prescription fills, and the 300 most common (60% of 500) represent an astounding 97% of all prescription fills:

Of course, the inverse relationship also holds true — the “bottom 200 drugs” (the 200 least frequently filled medications in the U.S.) represents less than 3% of all prescription fills in the United States.

How was the DrugStats database created?

The DrugStats database is produced based on data from an annual survey conducted by the U.S. Government called the Medical Expenditure Panel Survey (MEPS). While this survey data is publicly available for free, an extensive process of sanitizing the data and standardizing the drug products is required in order to produce the DrugStats database:

Introducing the Top 200 Drugs and Top 300 Drugs of 2017

ClinCalc.com is excited to announce the 2017 Top 200 Drugs and 2017 Top 300 Drugs, both of which leverage the DrugStats database. These two drug lists represent the most commonly filled outpatient prescription medications in the U.S. market using data collected from the MEPS survey in 2014.

Historically, the “top 200 drugs” was an annually published list using IMS Health data, which costs several thousands of dollars to subscribe to. Because these data have not been published in more than five years, there has not been an “official” top 200 drug list in quite some time.

Now, with the use of the ClinCalc DrugStats database, a freely available, objectively produced, and annually updated “top 200” and “top 300” drugs list is now available to the public.
